. so designed as to deect water squeezed from the A nother object is toprovide a clothes feeding device for wringers in which ,an endlessconveyor is utilized for carrying clothes into receiving relation withthe wringer rolls and in which'the conveyor or feeding device isoperatively connected with the wringer rolls for actuating purposes.

A further object is to provide a wringer feed in the nature of anendless conveyor operatively connected with the wringer rolls fordelivering clothes into receiving relation with the rolls and in which awater deflecting platel is associated with the conveyor and so relatedto the wringer as to be adjustable to permit wringing from positions oneither side of the Wringer.

Another object is to provide a wringer feed including a clothes feedingelement and guards associated with the wringer rolls in such manner asto protect the user from accidental injury as frequently happens inconnection with ordinary,

clothes wringers when the fingers, hair, etc., are caught between therolls.

In the accompanying drawing:

Fig. 1 is an elevational view of a wringer embodying my invention;

Fig. 2 is a sectional view along the line 2-2 of Fig. 1;

Fig. 3 is a sectional view along the line 3 3 of Fig. 2; and

Fig. 4 is a sectional view along the line 4-4 of Fig. 2.

In the embodiment selected to illustrate my invention, I make use of aconventional wringer I0 which includes the two upright frame members I2and wringer rolls I4 and I6. The rolls 'I4 and I6 as well as the wringerframe structure are conventional and well known in the art. According toFig. 1, the bottom roll I6 may be operatively connected with a powerdrive indicated generally at I8, but which forms no part of the presentinvention.

Frame members I2 carry a water deflectingl plate 20 which slopesdownwardly and outwardly from the central area 22 located directlyunderneath the roller assembly. Thus, the plate 20 is clothes by therollers in either of two directions depending upon the direction ofrotation of the rolls. Such rolls may be rotated in either direction topermit wringing from either side of the device.

- In Figs. 2 and 3, I illustrate the plate 20 as including side flanges24 which are secured to the frame members I2 by bolts 26. Between theframe members I2 I mount a straight plate 28A which includes sideflanges 30 pivotally connected on the bolts 32 threaded into thev'flanges 24 (see Fig. 3). Between the iianges 30, I mount two parallelrolls 34. These rolls may comprise shafts 36 provided with rubbercovering 38 with the ends of the shafts terminating in close relationwith the thickened areas 40 of the flanges 38. The shafts 36 are boredat 42 for loosely receiving the bearing shafts 44 comprising extensionsof the bolts 46 having threaded relation with the areas 40. Shafts 36rotate freely on the bar ing shafts 44, but the rubber coverings 38 arexedly connected with the shafts.

An endless belt or feeder 48 passes around the rolls 34 and between thewringer rolls I4 and I6.

According' to Fig. 2, the belt 48 is taut and its lower reach 50 isarranged in spaced relation with the plate 28. Belt 48 is pinchedbetween the rolls I4 and I6 to be actuated thereby. I prefer to make thebelt 48 of elastic material such asrubber. Rotation of the belt 46continues so long as lthe rollers I4 and I6 are in operation, whetherarranged' in pressure relation-according to Fig. 2

or when separated as when clothes are passing therebetween. i

The pivot bolts 32are located directly underneath the roll I6. while therolls 34 are so positioned with respect to altitude as to cause the belt48 to have two reaches 52 and 54 which are angularly related to thereach'50. 'I'he plate 28 may be pivoted about its axes 32 from the fullline position to the dotted line position of Fig. 2. According to thefull line position of Fl'g. 2, the wringer rolls I4 and I6 are beingrotated in the direction of the arrows 56 and 58, at ywhich time thereach 52 of the belt 48 travels in the direction of the arrow 60 forfeeding clothes into pick-up relation with the rolls I4 and I6. With theparts adjusted according to Fig. 2, the plate 28 parallels the angularreach 62 of the plate 20 so that water wrung from the clothes in theirpassage through the rolls I4 and I6 willflow downwardly on the reach 52as well as on the plate 28. While the plate 28 in combination with thebelt48 and its mounting is substantially balanced, the additional weightof wet clothes on the reach 52 is more than sumcient to hold the feeddevice in the full line position of Fig. 2, whereby the parts areadjusted in drainage relation with respect to the rotation of thewringer rolls I4 and I6.

When wringing clothes from the opposite side of the wringer, the plate28 is pivoted to the dotted line position of Fig. 2, at which time theangularity of the belt and the plate 28 is changed to provide drainagefor the water wrung from the clothes. In utilizing rubber for the belt5&8, Water flows freely therefrom and any stretch imparted to the beltbecause of variable thickness of material passing between the rolls i4and i6 is taken up immediately upon passage of the material through theWringer. According to the arrangement of Fig. 2, very little stretch isimparted to the" belt. In pinching'the belt between the wringer rolls,positive action is imparted thereto which insures effective delivery ofthe material to the wringer rolls. Material is deliveredinto pick-uprelation `with the wringer rolls by merely dropping the material uponthe belt li. In this way, small articles may be effectively delivered tothe wringer rolls without the aid of the hand or other instrumentality.At the same time, the belt operates in an eiective manner on largegoods. Because of the angular reaches 52 and 54, I attain large throats5d which facilitate entrance of the material to be wrung.

In addition to the wringer feed so far described, I provide additionalprotection in the nature of two plates 66 which are located on oppositesides of the roll U3 and terminate in close relation with the reaches 52and Eli of the belt 48. Plates 66 are hingedly connected at 68 withplates 18 attached to the flanges 12 of cross plates 14 which are boredat 16 for loosely receiving the ends 18 of the shaft 80 upon which theresilient body 82 of the roll 40 is secured. Plates 10 are secured tothe flanges 12 by bolts 84 and the ends of the plates extend partlyacross the frame members i2 as at 8G for guiding purposes. In connectingthe cross plates 14 with the shaft ends 18, the cross plates will moveup and down with the roll I4, thus adjusting the hinged plate 68 toaccommodate material of variable thickness. Plate 1li may be bentinwardly to extend partly over the roll M as at 88, in Fig. 2. While theshaft ends 18 rotate within the openings 16 in the cross plates, thelatter are restrained from relative pivotal movement because of theoverlapping relation between the extensions 86 andthe frame members l2.

Hinged plates 66 are of such width as to make it impossible for the handto be inserted between the wringer rolls I4 and i6. However, the platesmove about their axes in contact with the goods to be wrung so as topermit the goods to be brought into pressure relation with the wringerrolls. y

My invention embodies a wringer feed so de signed as to be capable ofassociation with wringers of conventional design and the feed inaddition to delivering goods to the wringer rolls is so related theretoas to eliminate the necessity for an additional drive. The wringer feedincludes elective drainage for water wrung from the material passingthrough the wringer rolls and is so designed as to accommodate the feedof clothes from either direction. Hinged plates 86 embody an additionalprotective feature which co-operates with the wrnger feed in such amanner as to prevent accidents such as are incident to unprotectedwringer rolls of conventional design.

Without further elaboration, the foregoing will so fully explain myinvention that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service.

I claim:

In combination, a supporting frame, a pair of Wringer rolls arranged inpressure relation and rotatably journaled in said frame, one of saidWringer rolls including a shaft projecting beotally connected with saidframe, rollers carried by said plate, an endless feed belt passing aboutsaid rolls and between the Wringer rolls to be driven thereby, a platesupporting frame movably related to said first frame, and plates hingedto said hinge supporting frame on opposite sides of one of said wringerrolls, said plate supporting frame having openings for the reception ofsaid shaft and being provided with guide means cooperable on said rstframe to restrain the plate supporting frame from rotation about ahorizontal axis.
